METHOD OF OXIDISING MERCAPTANS, THIOPHENIC COMPOUNDS AND DERIVATIVES THEREOF IN PETROL, KEROSENE AND DIESEL FRACTIONS

摘要

The invention relates to a method of oxidising mercaptans, thiophenic compounds and the derivatives thereof present in petrol, kerosene and diesel fractions. The inventive method is characterised in that it consists in oxidising sulphur compounds using organic or inorganic peroxides in a single liquid phase which comprises one of said fractions and an oxidising agent selected from peroxides and hydroperoxides and which is brought into contact with a catalyst based on solids which are amorphous to X-rays and which contain at least Si and Ti and, preferably, silicon bound to carbon.
